LAY R GOING PART OF POWER-LOOMS FOR WEAVING DOUBLE PlLE FABRICS.

SPECIFICATION forming part of Letters Patent No. 352,425, dated November 9, 1886.

Application filed April 17, 1833. Serial No. 91,984. (No model.) Patented in England April 13, 1881, No. 1,612.

To all whom it may concern:

Be it known that we, JAMES PRIEsTLEY, FREDERICK PRIESTLEY, and GEORGE PRIEST- LEY, subjects of the Queen of Great Britain,

residing at Bradford, in the county of York,

England, have invented new and useful Improvements in the Lay or Going Part of Power-Looms for Weaving Double Pile Fabrics, (for which we have obtained a patent in IO Great Britain, No. 1,612, dated the 13th of April, 1881,) of which the following is a specification.

This invention relates to improvements in the going part or lay of power-looms for weaving doublepile fabricsnvhereby agreater length of pile can be produced than by looms hitherto in use, and the pile-thread is held tight between the two fabrics during the operation of weaving.

To carry out our invention we cut away a large portion of the solid part of the lay or going part and insert small steel plates set up on edge. Each plate reaches across the cutout part of the lay, and the tops of all the steel 2 plates are in a'line and carry the shuttle when in operation. The warp-threads of the bottom fabric drop into the spaces between the steel plates, and are well out of the way of the shuttle when the top or upper fabric is being woven, and at the same time the pile-threads are kept tight and at full stretch between the two fabrics.

Referring to the drawi ngs, Figure 1 represents a sectional side elevation of a portion of the going part or lay of a loom which is fitted with the steel plates hereinbefore mentioned. Fig. 2 is an elevation, and Fig. 3 a plan of a portion of the same.

Similar letters refer to similar parts in each drawing.

The going part A, supported by the lever or sword B, has a longitudinal space cut away of sufficient width to allow the warp-threads for the bottom fabric to drop in. Upon the bottom of this cut-away space is fixed a long nar 5 row strip of iron, F, to which strip the small steel plates E are secured by dovetailing or by being forced into grooves. The tops of these small plates, which are uniformin height, are on a level with the bottom of the shuttle boxes, and the shuttle passes along on the tops of these plates in its traverse across the loom.

. The reed O is'fixed immediately at the back of the steel plates, and the bottom warp-thread,

K, after it passes through the reed 0, passes between the small steel plates, and is only raised 7 up out of these spaces when operated upon by the healds, as required for weavingthe bottom fabric. The top-fabric warp-thread is represented at J, and the taking-up roller for this 6c fabric at G. The'bottom fabric is taken up by: the roller H.

By the apparatus herein described we are enabled to produce a greater length of pile than heretofore, and the said pile 1s always 6 tight or at the desired tension in and between the two fabrics.

In looms for weaving double pile fabrics, the combination,with the lay-beam A, having 0 a reduced or cut-away portion,of the series of steel plates E, secured in such reduced portion, and permitting the warp-threads of the bottom pile fabric to drop into the spaces between Such plates, all as set forth.
